BAG-HOLDER.

Specification of Letters Patent. Patnted June 12, 1917,

To all 'whom t may concern:

Be it knownthat I, CARL G. G. Bitnes'rnoM, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Bag-Holders, of which the following is a speciication.

This invention relates to certain new and useful improvements in bag holders, and more particularly to'that class of devices which are' especially designed to support receptacles, suclras bags, sacks, and the like, in proper position to most conveniently receive articles to be placed therein.

An object of the invention is to provide a device for the purpose, comprising .novel means about which the mouth of a collapsible receptacle of any size may be easily and quickly attached in open position for the ready insertion of articles. l

Another object is to provide a support for the receptacle supporting means which may be adjusted in height as found desirable and which may be positively locked -in selected position.

A further object is to provide such a support comprising sliding or other members having means under tension for normally retaining them in adjusted positions, but which permits their rapid sliding movement with respect to one another to facilitate the filling of the bag.

Other and further objects and I advantages of the invention will be hereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings: j

Figure 1 is av side elevation of theinvention partly in section 'and broken away,

showing a bag held vin filling position" thereby Fig. 2 is a plan of lthe invention, with=` some of the partsremoved;

Fig. 3 is a partial end elevation lookingin the direction of arrow shown in Fig. 1; and

Fig. 4 is an enlarged section taken on the' a suitable base or platform B from which it extends vertically. Disposed for sliding movement upon the bar 1, is a comparatively short tubular member 2 having interior, longitudinal channel ways 3 within each of which one of the radial projections 4 of the bar loosely lit as clearly indicated in Fig. 4. The tubular member 2 is composed of two sections 5 and 6, the upper extremity of the section 5 being enlarged and interiorly screw threaded to coperate with the threaded adjacent end of the section' 6'as shown at 7 in Fig. 1. Near its enlarged portion, the section 5 is provided with a pair of spaced outstanding lugs 8 between which is pivoted one end of a dog19, the other end of which has formed thereon a tooth 10 which engages with the waved serrations 11 formed on the outer edge of one of the radial projections 4 of the` bar. By providing serrations of the wave type, it will'be understood that the dog 9 may freely ride along such surface in either direction as may become necessary to properly pack the produce placed in the bag to be filled as will hereafter more fully and at large appear'. At or near its lower end, the section 5 has secured thereto the ends of a U-shaped member 12 through the portion 13 of which is formed a threaded aperture to receive a bolt 15 having a short reduced inner end 16 about which a helical spring 17 is positioned, one extremity 18 of the spring resting against the end of the larger portion of the bolt and the other extremity 19 of the spring pressing against the adjacentl face of the dog to tensionally retain the same Vin engagement with the serrated surface 11 of the projection 4 of the bar vand Athus hold the member 2 in different adjusted positions with respect to the bar:

vOn the upper face of-one of the parallel armsl of ythe U member 12 are a pair of spaced lugsv 20 between which is pivoted a finger 21 adapted to be thrown into horiis brought to bear and the locking finger is released. Normally, however, the tension of the spring 17 is ample to hold the parts in selected position, the bolt 15 afford-ing means for regulating the tension of this spring as may be desired.

Suitably secured about the section 6 of the tubular member 2 is a split collar 23 from which project arms 24 supporting at their projections 4 on opposite sides of they bar so as to guide the yoke inits movements. Extending outwardly from a face of the yoke are two lugs 29 between which is journaled the angle portion of a bell-crank comprising a pair of elongated diverging arms 30 of equal length, the free end of each of which is provided with an aperture 31, through each of which extends a stud bolt 32 for fastening between the arms 30y a U shaped member 33 as shown in Fig. 2. Pivotally secured at one end by means of the stud bolts 32, on the opposite face of each of the arms 30 is' a straight rod 33" extending in a substantially horizontal plane therefrom and which passes between flanges 34 formed on the opposite ends of the jaw 25. It will also be noted that the free ends o f the U-shape member 33 are bent outwardly and abut the rods 33 to further increase the rigidity of the parts. At their free ends, the rods` 33 carry an iron jaw 35 similar to the jaw 25, except that the convex faces of the two irons are oppositely disposed and that the teeth 36 of the jaw 35 project in an opposite direction from that of the teeth 26 of the jaw 25. As shown, the jaw 35 is rigidly held upon the rods 33 by means of nuts 37.

rl`he short arm 38 of the bell crank is provided with an aperture 39 by means of which one end of a helical spring 40 is attached, the other end of the spring being secured through the medium of an eye-bolt 41 to a projection 42 projecting from the yoke 27. By this construction the tension of the spring may be readily adjusted by turning the nut 43 with which the bolt i provided.

When it is desired to place a bag, represented by the reference character C, in filling position uponl the device, the jaw 35' is forced inwardly, the mouth of the bag, or a portion thereof, secured upon the teeth of the jaw 25, and when the jaw 35 is released, it will move outwardly due to the tension of the spring 40 and its teeth 36 will engage a portion of the mouth of the bag in such manner as to hold it in distended position ready for filling.

Should it be desired to iirmly pack the produce or articles in the bag, as when the same has been partially filled, this may be accomplished by grasping the rods 33 and the adjacent portion of the bag and reciprocating the tubular member and its attached parts rapidly up and down upon the bar 1.

In order to evenly distribute and regulate the movements of the carriage mechanism for the movable bag supporting jaw 35, such mechanism including the rods 33', a pair of evener rods 41 areA provided, each of said rods being pivoted at one end as at 42 to one of the diverging arms 30 and at its other end between a pair of spaced lugs 43l carried by the stationary collar 23 by means of a threaded bolt 44, it being understood that each of said lugs is integrally secured upon the collar to opposite sides of the break therein so that the collar may be tightly held or loosened, as desired, with respect to the member 2 through the medium of the bolt 44 as will be understood. The object of the evener rods 41 is.l to effect a respective up or down movement to the yoke 2.7 when the carriage mechanism is moved in toward or away from the supporting standard 1 and in this way to edectu-ally eliminate any binding tendency of the parts in their several movements.

Loose-ly mounted upon the member 2 above the stationary collar 23 is a second collar 45 having an arm 46 extending therefrom to the fiee end of which is secured by means of rivets 48 or other suitable means, a guide chute 47 of any suitable conguration, but, as shown, it is of semi-circular shape and designed to facilitate the placing of the articles or produce within the bag. A plurality of spaced slots 14 one being j shown, are formed in the lower edge of the collar 45, and into any one of which a lug 49 formed on the member 2 is adapted` to seat. When it is not deemed necessary to.` use the chute, it may be turned about on the member 2 into inoperative position. Y In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth with in the scope of the following claims.

Having described my invention what I claim as new and desire to protect by Letters Patent is:
